Google Mapping Only clear skies on Google Maps

Google Mapping Only clear skies on Google Maps and Earth

June 26, 2016
To celebrate the sunny days of summer (in the northern hemisphere at least). We’re unveiling new satellite imagery for all Google mapping products today. This stunning new imagery of the earth from space virtually eliminates clouds, includes refreshed imagery for regions of the world where high-resolution imagery is not yet available. And offers a more comprehensive and accurate view of the texture of our planet’s landscape. Google mapping 2

The new, even more beautiful global view in Maps and Earth.

In 2002 NASA released the Blue Marble, a global image of the earth with a resolution of one kilometer per pixel, based on data from NASA’s MODIS instrument. Updated in 2005 to twice the resolution, it has remained the canonical globally-uniform picture of the earth for over a decade.

With the Blue Marble as inspiration, we used Google Earth Engine technology to mine hundreds of terabytes of data from the USGS’s and NASA’s Landsat 7 satellite. The result is a seamless, globally-consistent image of the entire planet with a resolution of 15 meters per pixel, far finer than is possible with MODIS data alone.

To get a feel for the difference, here’s a comparison of the Grand Canyon, first from the Blue Marble Next Generation (courtesy NASA’s Earth Observatory), and then in our new Landsat-based imagery.Google mapping

The Grand Canyon, as seen by MODIS and by Landsat 7.

The Landsat 7 satellite suffered a hardware failure early in its life that introduced striped artifacts into all of its images. By analyzing a large number of images we were able to virtually eliminate these stripes, as well as clouds and other atmospheric effects. The process was very similar to how we produced theglobal time-lapse imagery of the earth that we released last month. Google mapping castellon

Castellón, Spain: One example Landsat 7 image, and the final combined image.

The resulting 800,000 megapixel global image is so big that if you wanted to print it at a standard resolution of 300 dots per inch. You would need a piece of paper the size of a city block! Google mappingGoogle mapping south america

Northwestern South America: before and after.

Mining data from a large number of Landsat images of each area allowed. Us to reconstruct cloud-free imagery even in tropical regions that are always at least partly cloudy. Google mapping papua

Central Papua, Indonesia: before and after.

We prioritized recent data when it was available. So this update also includes refreshed imagery in many regions of the world. Especially in areas where high-resolution imagery is not available. Including parts of Russia, Indonesia, and central Africa. Google mappingGoogle mapping saudi arabia

Agricultural expansion in Saudi Arabia: before and after.

This new picture of the earth also reveals the texture of the landscape with greater clarity than ever before. Google mapping brazil deforestation

We’re proud of the progress we have made, but there is always room to keep improving. For example, although we have tried to minimize the impact of the stripe artifacts in the Landsat 7 images. They are still visible in some areas. There is more good news though: the new Landsat 8 satellite. Launched earlier this year, promises to capture even more beautiful and up-to-date imagery in the months and years ahead.

You can see our new satellite imagery by going to Google Maps and turning on satellite view. Or by launching Google Earth. And zooming out. Have fun exploring!

3D trees in the western United States

3D trees in the western United States

3d trees arbres D Arbres bAugust 31, 2011

It’s late summer and many U.S. cities have reported record (or almost record) heat. Are you withering in warmth and longing for some shade under a tree?. Maybe you can’t easily leave for your favorite park but trees are actually closer than you think! We’re happy to announce that we’ve added 3D trees to Google Earth in three new cities: Los Angeles, Denver and Boulder.Typically, when you imagine trees in Los Angeles, you picture the commanding palm trees that line the famous Hollywood avenues or dot the gracious mansions of Beverly Hills. While Palm Trees may dominate the landscape, there are actually many other trees both native and foreign that inhabit the city, such as the California Oak, Black Walnut trees, and California Sycamore (to name a few).

You can now get a glimpse of these trees with the new 3D tree models covering the West Side, including cities like Santa Monica, Beverly Hills, and Hollywood, as well as parts of downtown where the financial district sits. Check out the famous Sunset Boulevard which stretches from the sea at Santa Monica to downtown. Here is where you will find Palm Trees lining glitzy movie posters and billboards that are a marquee signature of the city.

Or jump to the see more native species like the native Oak tree species in Elylsian Park adjacent to Dodgers Stadium.

There are two species you absolutely can’t forget when talking about trees in Colorado:.  Colorado Blue Spruce and Quaking Aspen. Both native to Colorado. Colorado Blue Spruce has a very distinct look for the pale blue of its needles. It is also the Colorado state tree and a very common tree species seen in the Colorado Foothills. Quaking Aspen got its name from fluttering leaves in the breeze. And makes up the famous golden fall foliage of Colorado. Take a walk on Cheeseman Park in Denver or a fly over Boulder and you can tell these trees by their unique colors and shapes.

There is one other tree species in Colorado deserving a special mention – Cottonwood trees in Boulder. Every late spring, these trees cover Boulder in white cottons. Making it feel like it’s still snowing in June (although that could happen in Colorado). There are several Cottonwoods right by the Google Boulder office that create white blankets of cotton in our garage. And on sidewalks every June and July. Looking at these 3D trees on Google Earth makes me feel like sneezing all of a sudden…
